Wood Identification

Anatomic Description Of Wood

Wood diffuse porous. Vessels solitary and in short radial multiples. Tangential diameter of vessel lumina 200 micras or more (large). Tyloses common. Vessels per mm2 less than 6 (rare). Simple perforation plates. Vessel-ray pits similar to intervessel pits in s Axial parenchyma in marginal or in seemingly marginal bands. Axial parenchyma in continuous tangential lines (included in reticulate and scalariform). Prismatic crystals in chambered axial parenchyma cells and/or in fibers. 5 to 8 cells per parenchyma strand 4 to 10 rays per mm (medium). Rays 1 to 4 seriate. Homogeneous rays and/or sub-homogeneous rays (all ray cells procumbent). Fibers with simple to minutely bordered pits.
